¡ Marfan syndrome is an inherited disorder that affects connective tissue — the fibers that support and anchor your organs and other structures in your body.
¡ The protein that plays a role in Marfan syndrome is called fibrillin-1.
¡ Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1.
¡ This mutation causes problems in connective tissues throughout the body.
